Question

Part 1)
The initial speed of a body is 8:08 m/s.
What is its speed after 1.54 s if it accelerates
uniformly at 3:03 m/s2? Answer in units of
m=s.

Part 2)
What is its speed after 1.54 s if it accelerates
uniformly at -3.03 m/s2? Answer in units of
m=s.

Answer 1

v(t)=vi+a*t

1) v(1.54)=8.08+3.03*1.54

2) v(1.54)=8.08-3.03*1.54

Answer 2

Relative speed of trains(u) = 30 + 30 = 60 km/hr =>time of collision (t) = s/u = 60/60 = a million hour =>hence the gap lined by utilizing chicken (s) :- =>by utilizing s = v x t =>s = 60 x a million = 60 km
